Jolida JD100 better that the Rega Planet 2000?

So I am getting ready to sell my Rega and buy a Jolida.
If given the choice would you move to a JD-100 from a planet 2000 or keep the Rega?

I am entirely going on faith here, as I have never heard the Jolida.
I was looking for tubes for it to start with. People keep saying that the GE 5751 is good. On partsconnexion.com they sell the GE 5751 NOS for about $18 each. Is this the right tube (never owned tube so I just thought I would ask)? And do the tubes have to be matched.

Thanks,

Here are a few questions I also have

When do tubes have to be replaced? After so many hours or once they stop working? How will I know when tubes need replacing? How long will most tubes last for if left on 24/7 in the Jolida.

Is their any risk of a tube blowing an talking my amps and speakers with it?

Once I get the Jolida I am probably going to want to try other tubes. Is there somewhere I can go to read what all the different tubes sound like?

Also, if there is anything else about tubes I should know please feel free to inform me. I really am clueless about tubes, as currently I am all solid state.

Thanks,
Nick

Nick,
Here is some recent discussion on tubes for that player:
http://forum.audiogon.com/cgi-bin/fr.pl?ddgtl&1112895895&read&keyw&zztubes+jd-100

The 12AX7 is said to last around 10,000 hours in that player. When a tube goes bad, you will likely hear nothing more than diminished sound quality.

You can check out Joe's Tube Lore on Audio Asylum, under FAQ (I believe) to get an idea of the different sonic characteristics of the various 12AX7/5751/etc. type tubes.
If you listen mainly to jazz/vocals/instrumental, I might suggest that you try the Mullard CV4004 or 12AX7 variety. They are quite liquid sounding, milky even. You give up a little when it comes to rock, but not much. If you like a more focused, detailed sound, I would suggest trying out the GE/RCA/Sylvania 5751 tubes. Telefunken 12AX7's also have similar qualities--to MY ear, anyways. In the Jolida, I preferred the Mullards, as I found the music to be most engaging with them. Also, it's important to buy from a reputable source (check the archives). Otherwise, you can end up with bad tubes and/or paying far too much.

Finally, why not hang on to the Rega until you know that you definitely want to keep the Jolida? When we bought our JD-100, we sold our Planet 2000 the next day. However, you may not end up doing the same. Just a thought.
Enjoy,
Howard

Thanks Boa2, you have been a lot of help.

I am not really sure what I want for tubes. I can tell you my musical preferences and maybe you can help. First off, I listen to all types of music from Classical to Metal.
I spend most of my time listening to light rock.

I guess I am wanting a a neutral tube.
Something that is open and natural, has some warmth, full body sound, with good extension on both ends.

I don't like it when the sound is thin, dry, or sounds really congested with no soundstage. I also don't like rolled of highs or lack of bass (I am not a bass freak, but I do like there to be enough to do justice to the music). I also don't like dark sounding equipment either, nor do I like anything bright.

When I listen to music i like to be able to connect with the artist. I am not a detail freak, I like to be able to hear the subtle nuances in the music, but I still like the slam of an orchestra.

I guess what I want is something that does everything well. With a minor preference on openness and naturalness (with a little warmth.)

Does that help at all? Probably not but hey, I tried.
I have heard good things about new EH tubes?
What do you think about them.

Many thanks, as I really am clueless when it comes to tubes.

P.S. The reason I am not keep the rega is: I can't afford to buy the Jolida and keep the rega. The Rega must go to help pay for the Jolida. So unless someone on here wants to lend me a grand for a few weeks I am out of luck. Thus my one million question, as I just want to be sure.

Based upon your sonic requirements--and genre preferences--I would suggest trying either the Sylvania 5751 or Telefunken 12AX7. Others can chime in with suggestions, but I think either of these will answer to your stated needs. E-mail me privately, and I can send you some Telefunken's to try out.

Haven't heard the new EH's. I've never heard an EH tube that I liked, though I certainly could be surprised sometime by one that works for me. Every one that I've heard thus far sounds ashy and thin to my ear.
Enjoy the Jolida. It's an excellent player.
